Reaction Conditions:

in N,N-dimethyl-formamide at 50; for 3 h;

Steps:

24.1 Step 1: Synthesis of 5-bromo-2-(methylthio)pyrimidine

Step 1:
Synthesis of 5-bromo-2-(methylthio)pyrimidine
To a stirred solution of 5-bromo-2-chloropyrimidine (0.3 g, 1.563 mmol) in DMF (10 mL) was added methyl mercaptan (0.1 mL, 1.563 mmol) at room temperature and heat at 50° C. for 3 h.
Completion of reaction was monitored by TLC.
Reaction mixture was quenched by addition of water, extracted with EtOAc.
Organic portions were combined, dried over Na₂SO₄, evaporated under reduced pressure to obtain crude which was purified by column chromatography using silica gel (100-200 mesh); eluent 5% ethyl acetate/hexane to obtain pure product 5-bromo-2-(methylthio)pyrimidine (0.240 g, 75%) as white solid.
